I would LOVE to have a set schedule, but I haven't had a set TANK! (I'm brand new at fish keeping.) Anyways, I'd love to know what the best schedule WOULD be to clean out my 3 gallon tank which has a filter.

Once a week cleaning (partial water change) and gravel vacuum would be sufficient ;)

With a 3 gal tank, you'll still probably need two water changes weekly. One with a gravel vac and one without.

Since all of my tanks are cycled, I just do one water change per tank per week. With all of my tanks this equates to about 70 gallons of water as I don't just have betta tanks. I've also got a community and a goldfish tank.

Since I currently only have bettas in unfiltered tanks, I do one 50% change on a set day for a certain number of tanks (I have nine, so three every day for three days), and then a 100% change for those same tanks three days later (ie. 50% on Monday, 100% on Thursday).

I also have one boy in a 1.5 gallon bowl (it's a thing-- he does best in smaller spaces), and two other boys recovering their fins in similar bowls, so those get 100% changes every two or three days.

For my girls, they're all in different sized bowls while the tanks cycles up. The 3 gal bowl/tanks get 2 50% changes and 1 100% change over the course of two weeks. For the 1 gal bowls, they get 1 50% and 1 100% change each week. For the 1/2 gal bowls (I know, I know... it's temporary.) they get 2 50% changes and 1 100% change per week.

I keep track of it all on notecards. I write down when I do a change and also how much. Each bowl has a card. Every morning I sift cards and decide who needs cleaning. It's tedious, but temporary.
